ARCH-SUPPORT.

Specification of Letters Iatent.

Patented Feb. 20, 1917.

Application filed June 23, 1916. Serial No. 105,341.

To all whom it may concern:

Be it known that I, WILLIAM M. SoHoLL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Arch-Supports, of which the following is a specification.

My invention relates to improvements in arch supports, and has for its general object to provide an arch support structure that facilitates adjustment to accommodate the peculiarities of the foot of the wearer; that insures its remaining in adjusted condition and that, in use, adequately maintains it in proper relation to the foot.

In the drawings wherein I have illustrated an embodiment of my invention,

Figure 1 is a bottom plan view of an arc support structure constructed in accordance with my invention.

Fig. 2 is a side elevation of the metallic plate, and

Fig. 3 is a section through the metallic plate on line 3-3 of Fig. 2.

In the construction shown 10 indicates acover piece of leather shaped for conformity with the heel and shank portions of a shoe and having attached thereto as by rivets 11 an arch plate 12 having a side wing 13, and having also, preferably, a lateral extension 14: toward the outer side of the foot. The arch plate has longitudinal and transverse curvatures in substantial conformity with the plantar surface of the human foot that it underlies, its highest arch portion usually being at the inner side of the shank portion of the plate where the side wing 13 arches highest. The side wing 13 is preferably provided with a series of apertures 13 wholly within the confines of the plate and separated by transverse bars 15. The arrangement that the uninterrupted rim 16, which forms the crown or curved e and has its inner curvature interruptedlydefined by the edges of the apertures 15, is of maximum width at the highest portion 17 and tapers 'n width toward its extremities 18 and 18, so that inherently the rim portion 17 is stifiest at its center and of decreasing stiffness as it approaches its ends; while, preferably the posts 15 respectively decrease in length and increase in width from center to end, so that with respect to the posts alone, the we kened area of the wing in which they lie is broadest and weakest near provided is preferably such dge of the side-wing the center. Thus in the integral wing structure of the plate there are provided two zones for adjustment, the one being the crescent-shaped zone of the'posts 15 and the other the crescenthaped zone of the rim 17, the width of each zone increasing from the ends thereof toward the center. By such construction, it will be seen, the leather cover piece is afforded support throughout both zones adequately to give a smooth and unbroken surface to the foot, the area of easy adjustment established by the provision of the openings 13 is made of maximum width adjacent the longitudinal center 0 the area, and preferably the attenuation of the connectionbetween the rim and body of thewin g, increasing toward the longitudinal h center of the wing, 1s partly compensated for by increasing width of the rim portion of the wing from its ends toward its center. A wing portion so constructed may be adjusted with great nicety to the precise requirements of the foot of the wearer with the insurance that notwithstanding its slight, and in many instances desirable, springiness, it will maintain its adjusted shape even under conditions of severe strain.

In instances where it is desired to limit the area of adjustment to the wing, and to lend rigidity and strength to the body or axial portion of the arch plate, a concaved rib 21 may be provided in the body portion preferably extending beyond the apertured area of the wing and at its ends merging into the body of the plate; and, further, to assist in insuring the proper positioning of the plate with the foot of the wearer, the extension 14 may have its end upturned as at 214: to engage the outer side of the foot of the wearer near the heel and prevent displacement of the arch plate toward the inner side of the foot.

While I have herein described a particular embodiment of myrinvention for purposes of full disclosure it will be apparent to those skilled in the art that changes in the details of construction might be made without departure from the spirit of my inven-- and an apertured zone between the rim and body of the Wing, the last said zone lncludmg transversely rim with the body of the Wing, said posts affording a zone decreasing in strength from the ends of the liIl'ltOWiLId its middle and arranged posts integrally connecting the body of the Wing and rim.

longitudinally of said plate, and integral transverse posts connecting said said rim increasing in Width from its ends toward its middle.

4. The combination in an arch support plate, a body portion 12, Wing portion 13 having apertures 13, separating posts 15 that connect to the body of the Wing, an uninterrupted rim 1?, a reinforcing rib 21 and an upturned side extension 14L1t combined and arranged substantially as described.

In testimony whereof I hereunto set my hand in the Witnesses.
